Select the best answer below:

struct quizzes int Q1; int Q2; int Q3; double Average; Choose the best answer to accomplish this task:write a function which accepts a vector of structs and puts the average of the three quizzes in the Average field for each struct in the vector. O void averageQuiz(vector &V) int count 0; for(int i 0:i Vsize0:i++) V[i]Average = (V[i].Q1 +ViIQ2 + VIi].Q3)/ 3.0; void averageQuiz(vector &V) int count 0; for(int i=0;i
